Glutathione
A naturally occurring antioxidant studied for its role in supporting cellular defense, detoxification, and the body’s response to oxidative stress.
The body’s master antioxidant
Glutathione is a small molecule made of three amino acids that your body produces naturally in nearly every cell. It is often described as the master antioxidant for its central role in neutralizing free radicals, supporting detoxification, and protecting cells from oxidative stress. At Meridian it is offered in well-characterized forms — chosen for quality and bioavailability — and can be started directly, though we encourage a conversation with your physician first.
Supporting the body’s antioxidant defense
Glutathione works by donating electrons to neutralize reactive molecules that can damage cells — a process central to the body’s antioxidant defense. It also supports the liver’s natural detoxification pathways. It is typically taken as a daily dose, with the format chosen to suit your preferences and goals.

What the research explores
A plain-language look at the areas of study. Research is evolving and varies in strength — we present it honestly, not promotionally.
Glutathione’s role as a primary cellular antioxidant is well characterized in the scientific literature.
Research describes its part in the liver’s conjugation pathways that process and help clear compounds.
Studies on supplemental glutathione and its precursors continue to examine absorption and clinical effect.
Glutathione’s antioxidant biology is well established. As a supplement it is not intended to diagnose, treat, cure, or prevent any disease.
Our Science Library — evidence summaries, mechanisms, limitations, and provider commentary — is expanding.
Glutathione, answered
Glutathione is sold as a dietary supplement, not an FDA-approved drug. Supplements are regulated as foods and are not intended to diagnose, treat, cure, or prevent any disease. Injectable forms are prepared by a licensed pharmacy.
It depends on the format — commonly a daily oral or liposomal dose, and in some cases an injectable prepared by a licensed pharmacy. You’ll receive clear guidance for whichever form you choose.
No. Glutathione is available directly without a required provider visit. We still encourage you to consult your physician before starting, especially if you take medications or have a medical condition.
For a broader longevity routine, membership adds provider guidance, progress tracking, and check-ins over time — but it isn’t required to purchase glutathione directly.
